Common Problems of and Solutions to Sand Maker in Stone Production Line

As one of the large-sized mechanical machine, sand maker has wide application in many industries such as mining, chemistry, building materials and cement. After many years' research, the technicians find that sand maker has opened new application field and expanded to water conservancy project with constant innovation and technological reform. The water conservancy project has always been emphasized by our country, and its development will inevitably drive the development of a series of projects such as water and electricity projects construction and irrigation works, and will also drive the development of large-sized mechanical machines and promote the market demands for crushing machines and sand maker. During the process of vigorously building and developing hydropower stations, the need for superior sand and stone aggregates will be huge. The equipment that is used in the sand and stone production line includes impact crusher, jaw crusher and new type sand maker.

In the aspect of artificial sand making technology, in order to ensure the sand and stone aggregates with all granular compositions that are needed in power station dam roller compacted concrete, especially the mountain flour content in the final sand, HXJQ has rich experience in producing high quality artificial sand and stone aggregates that are used in large-sized water and power station, highway and high-speed rail construction and the sand and stone aggregates production equipment launched by our company has been widely used in many large projects. The launch of high quality sand and stone aggregates technology and new type sand maker equipment will bring about the green revolution of large construction projects such as water and power station, rapid transit railway and highway.

The stone production line is playing an important role in many industries, no exception for the sand maker. Due to various kinds of machines, what should we do in order to minimize the breakdowns of the stone production line? After the research of our technicians, we find that the common problems that influence the sand maker are:

(1) Unusual vibration may occur in the working process of sand maker. The causing reasons are that the driving bearing is seriously abraded, the catching of toothed wheels is not complete and the foot margin connection bolt is loose. The solution to the problem is to adjust the gap of the wheel gear, timely change the abraded part, re-fasten the bolt in order to ensure the stability of the machine in the working process.

(2) The materials slurry will leak from the connection part of the cylinder and the top cover of the sand maker machine. The reasons are the bolt of the machine is loose, the pin is too long and the sealing gasket of the equipment is seriously abraded. The solution to the problem is to fasten the loose part and change new sealing gasket.

(3) The power supply for the sand maker is not stable, and the reasons are the lubricity of the main bearing is weak, the materials feeding machine is loose, the density of the discharged materials is too high, the lining board is serious damaged or there is fault in the motor. The solution to this problem is to timely add lubricant to the rotary bearing, adjust or change the abraded device and examine and check the circuit of the motor.
